SRAM Red XG-1290 12-Speed Road Cassette 10-33T Silver — X-DOME, XDR Driver, Flattop Chain

The SRAM Red XG-1290 is the flagship of SRAM's 12-speed road range — an entire 10-33T block machined from a single piece of steel using SRAM's X-DOME process, so there are no pins, no carriers and no wasted grams. X-RANGE spacing gives five one-tooth jumps through the fast end of the cassette and still leaves a 33T bail-out for long climbs, all in 211 g. It drops onto any XDR driver body and runs with SRAM's Flattop 12-speed road chain.

Key Features

• ✓ One-piece X-DOME construction — machined from a single billet of steel for maximum stiffness at minimum weight
• ✓ X-RANGE gearing — 10-33T across 12 speeds for a 330% range with a 10-tooth start
• ✓ At least five one-tooth steps for smooth cadence changes at racing speed
• ✓ Requires a SRAM Flattop 12-speed road chain (D1 or E1) — standard 12-speed MTB/Eagle chains will not work
• ✓ XDR driver body only — the road-width XDR, not the shorter MTB XD
